I am new to the diesel world . I have had the truck for alittle over a year about 17k miles. I've had the high presure fuel pump repaired twice. i drove about 500 miles today and it ran fine till it went into regen - the cruise kicked off and wouldn't come back on ., The truck ran fine until I got on hill and got on it and it wouldn't get above 60 mph. The turbo psi gauge went to the middle and wouldn't go any higher , It sounded like I should have been going about 120 mph apprx 3500- 3750 rpms.I got home and feltt the big wastegate looking thing on the outer most radiator (I
presume its the intercooler ) I was very cool . Any thoughts ? I hope not another pump the last time they had it 31 days! I read some thought about cking the filters .I do that in the am

I don't have a 6.4, so i don't know what to tell you about the regen issue except to get a DPF delete and a custom tune. I will also suggest that if the pump dies again get yourself an Air Dog 2

Ckd the water seperator and only it only dripped out (thoufght maybe the fileers are clogged or something) . Started it up ,took a short ride and it ran like a scalded dog, Have no idea maybe the egr stuck or something.

[forddieseldoctor]

check codes. If the egr valve was sticking there will be a code. Plus there should be codes if it is something else.

[Shinny]

It's probably the EGR valve. They don't always throw codes when they go. Did you have any smoke from the exhaust?

[silverado08]

Couldn't tell it was dark ! I 'll ck to see if there are any codes today .

Fill with fuel, yaou can't drain the water separator with the tank at 1/4 or less...

HPFP problems could be water in the fuel, yes it could be defective manufacture but that is rare as rocking horse poo... Most likely poor diesel fuel quality/ water in fuel.

I had an imtermittent rough running problem on mine, just last week. This week, they replaced injector #4 when it failed the Power Balance Test. Codes P0266 and 2291. If it weren't under warranty, it would've cost $1097.99.
In areas with poor fuel quality, Ford requires that their diesel fuel additive be used to maintain warranty coverage. But, of course, they won't provide it for free. ;-)

They replaced the HPFP @ about 10k miles . Got it back and two days later it quit running . Apparently something with the wiring to the pump when the cab was put back. They also replaced #6 injector I think
